Early edition of Peurbach's Theoricæ Novæ Planetarvm. Together with the follow up work: Quaestiones In Theoricas Planetarum by Christian Wursteisen (Urstitius). Additionally a work by Regiomontanus, and one by Ioannes Essler, both of which are part of volume one's continuous pagination. Volume II with separate collation. Two volumes in one, small octavo

(6 1/4 x 4 inches; 160 x 100 mm). 16, 262 [ie 226], [2]; 16, 430 pp. With a total of 11 of 12 folding plates (more than usually found). One of two folding plates for book I (however it has been misbound into book II between pages 238-239 and cropped a bit short at the inner margin). With all 10 folding plates for book II. Numerous other astronomical woodcut charts throughout the texts, included in the pagination. Date and publisher from the Colophon. Title-page of Quaestiones with a separate woodcut vignette title-page. Quaestiones lacking final colophon leaf Dd8 as is common. WE can find no other copies at auction of this 1573 edition.

Bound in contemporary full limp pigskin. Yapped edges. Title in red ink manuscript on spine. Lacking original ties. Numerous old ink manuscript notes to front endpapers and on title-page of the first volume. Old ink marginalia throughout. A few instances of light dampstaining, mainly along top margin. Overall a very good copy of this important book on astronomy.

"Peuerbach’s best-known work, the Theoricae novae planetarum (1454; “New Theories of the Planets”), began as lectures to the Viennese “Citizens’ School” (Bürgerschule), which Regiomontanus copied in his notebook. An influential university textbook, the Theoricae novae planetarum eventually replaced the widely used, anonymous 13th-century Theorica planetarum communis (the common “Theory of the Planets”). By the late 17th century, this textbook had appeared in more than 50 Latin and vernacular editions and commentaries, while introducing such students as Nicolaus Copernicus (1473–1543), Galileo Galilei (1564–1642), and Johannes Kepler (1571–1630) to an updated and simplified version of Ptolemy’s Almagest that gave a physical interpretation to its mathematical models."
